Yamaha GP1200R Waverunner 2001 Owner's Manual

To winterize your Yamaha GP1200R, start by thoroughly cleaning the exterior and flushing the engine with fresh water. Use a fuel stabilizer in the gas tank and run the engine for a few minutes to circulate the stabilizer. Drain the cooling system and add antifreeze if necessary. Remove the battery, store it in a cool, dry place, and ensure it is fully charged. Finally, cover your Waverunner with a breathable cover to protect it from the elements.

The recommended maintenance schedule includes: checking the oil and fuel lines before each use, changing the engine oil every 50 hours or annually, inspecting and cleaning the spark plugs every 100 hours, and checking the jet pump oil every 50 hours. Additionally, inspect the hull and deck for damage regularly and ensure the battery is in good condition.

If your Waverunner won't start, check the battery for charge and connections for corrosion. Ensure the fuel tank has fresh fuel and the fuel lines are clear. Inspect the spark plugs for wear or fouling and replace them if necessary. Check the kill switch and lanyard to make sure they are functioning properly.

Overheating can be caused by a clogged cooling system, low coolant levels, or a malfunctioning thermostat. First, check for debris in the intake grate and flush the cooling system. Inspect the coolant level and top it off if necessary. If the problem persists, consider replacing the thermostat or consulting a professional technician.

Excessive vibration can occur due to debris in the impeller or damage to the drive shaft. Inspect the impeller for any obstructions and remove them carefully. Check the drive shaft for any signs of damage or misalignment. If the problem continues, it may be necessary to have the impeller or drive shaft professionally serviced.

Improving performance can be achieved by upgrading the impeller for better acceleration and top speed. Regular maintenance such as cleaning the hull, tuning the engine, and using high-quality fuel can also enhance performance. Consider installing aftermarket parts like a performance intake grate or ride plate for additional improvements.

Before using your Waverunner, check the hull for any visible damage, ensure the throttle and steering controls are functioning smoothly, and verify that the kill switch lanyard is attached and operational. Make sure the fuel tank is full and that all safety equipment, such as life jackets and fire extinguishers, are present and in good condition.

Clean the hull with mild soap and water after each use to remove salt, grime, and debris. For stubborn stains, use a specialized marine cleaner. Inspect the hull regularly for cracks or damage and repair them promptly. Applying a coat of marine wax can protect the hull from UV damage and improve water performance.

If your Waverunner is not reaching full speed, check the impeller and jet pump for debris or damage. Ensure the throttle cable is properly adjusted and that the engine is running smoothly. Inspect the spark plugs and replace them if they are worn or fouled. Additionally, verify that the air filter is clean and not restricting airflow.

For long-term storage, clean and dry the Waverunner thoroughly. Add a fuel stabilizer and run the engine for a few minutes. Remove the battery and store it in a cool, dry place, ensuring it's fully charged. Lubricate moving parts and apply a protective wax to the hull. Store the Waverunner in a dry, covered area to protect it from the elements.
